Dynamic performance of sensorless induction motor drives with two control systems based on multiscalar models

Application of the speed observer to two types of non-linear control systems of the induction motor is considered in the paper. The control systems are based on multiscalar models of the induction motor. Properties of the control systems are considered in dependence on two types of the multiscalar models of the induction motor pointed out in the paper. Simulations and experiments have confirmed the effectiveness of the proposed scheme
